Microsoft is pushing voice control -- waking and interacting with Copilot using just your voice, though you might want to note that you can already do this sort of thing online, and the results have one big caveat... to appear more responsive to voice input the models have been trained to skip a lot of the computations [thinking?] they normally do, so the results may be [even] less than hoped for.
And Copilot can now do stuff with the files on your PC/laptop, if as Ed Bott notes, you trust it to access your stuff and maybe break something.
These features are Opt-In.
